 John, my dell 45s came with 7850.9 idle jet holders and 55 idle jets.  I left the holders and put in the 58 idle jets to get rid of the stumble.  I still set the timing at 10 btdc.  All I can say is that every car is different.  My engine has never been rebuilt so the right setup for it may be different than one newly rebuilt.
